  • Demineralization of coal by stepwise bioleaching a

    A selective enriched mixed culture developed for this purpose was used for stepwise aerobic bioleaching of two high ash Indian bituminous coals (Topa coal and Godavari coal) and Neyveli lignite. The process of bioleaching resulted in the removal of more than 50 of the mineral matter in five repeated steps and thus produced relatively demineralized clean coal.
